After a lot of idea generation last night (WAST), I finally settled on an idea: You're teleported into a computer, and the only way to get out is to import a frontdoor (Not the hacking backdoor which lets you in. See what I did there?). However, there are different levels of useless data that are taking up space. So the game is simple: Destroy all useless data. However, if you wait too long, the data makes more useless data, using up more space.

If your computer runs out of space, you lose. :)

I'm entering the compo, so I'd better get going.
